SPIKE FASTENER.

Application tiled August e, 1921.

ha simple and efficient construction of spikes for use in connection with sport shoes and particularly those used inconnection with running, baseball and football shoes and the like, and more particularly to provide an improved means for securing or positioning the spike upon the shoe sole so as to prevent v the displacement or detachment of the same or the mutilation of the sole by reason of strains applied thereto, and with this object in view the invention consists in a construction and combination of parts shown in the accompanying drawing, wherein Figure 1 is a perspective view of a shoe sole inverted having spikes embodying the invention applied in the operative position thereto; Fig. 2 is a sectional view of the spike and shoe sole engaged thereby, the spike being shown partly secured; Fig. 3 is a view similar to Fig. 2 showing the spike completely secured, and Figs. e and 5 are sectional views showing modifications.

Referring specifically to the drawing, the spike consistsof a base or shank portion 10 extended to form the spike stem 11 which is pointed as illustrated but may be of any desired form, the said shank being provided with a head l2 consisting of a disk adapted to come in 'contact with the inner surface of the shoe sole 13. ln connection with the spike shank and as a means for holding the spike in place on the sole with the head 12 in tight bearing contact with the inner surface thereof, there is employed an eyelet 14 which is embedded in the sole 13,

and has its outer end flanged as shown at 15, said flange bearing against the outer surface of the sole. The iange 15 is therefore on one lside of the sole, whereas the head 12 is on the opposite side.

The eyelet 14 is preferably driven or hammered into the shoe sole 13 so as to be embedded therein, and to engage its iange 15 with the exterior surface of the sole.

ln the construction illustrated in Figures Serial N0. 489,787.

2 and 3 the eyelet 14 is interiorly threaded, and the shank 10 of the spike is threaded eX- ternally for engagement therewith, so that when the parts are united there is a definite interlocking relation between the shank and the eyelet, and the portion of the shoe sole 13 disposed within the area of the spike head 12 and the outstanding flange 15 is compressed or clamped there between.

A further means for securing the spike consists in forming the same with a shoulder 16, which latter, after the parts are assembled as shown in Fig. 2, is expanded by a suitable tool and forced outwardly to seat on the ange 15, as shown in Fig. 3. rllhis expedient firmly rclinches the spike and prevents all looseness.

ln the construction illustrated in Fig. l the screw-threaded connection is Vdispensed with, and the shank 10"L is given a slight taper, so that it is forced into the eyelet 14 by heavy pressure to obtain a frictional engagement therewith.

Fig. 5 illustrates another embodiment of the invention. Here the flanged eyelet 14 is left off, and the shoulder 16 is upset to bear directly on the outer surface of a washer 17 interposed between the sole 13 and the shoulder, the sole being thus firmly clamped between the washer 17 and the spike head 12.

1t will be noted in each form of the device the engagement is with the body of the shoe sole, with the interposed portion of the sole clamped or compressed throughout a Sufficiently large area around the spike to afford a substantial support for the spike and resist the transverse strains applied thereto notwithstanding the relative length of the projecting portions of the spikes.

l claim:
